## ZEISSTC_DSE

This probe changer is used with the DSE rotating head. It is defined as ZEISSTC_DSE. Calibration for this probe changer is done by placing the special probe changer Calibration Tool inside the slot.

In order for this probe changer to function properly, each slot must be assigned the same number as in the Zeiss software. So, if there are four slots (typically back to back) the proper setup would be:

1. Define ToolChanger1 with two slots.

2. Assign to Slot #1 the slot that Zeiss software calls Slot #1 (or A).

3. Assign to Slot #2 the slot that Zeiss software calls Slot #2 (or B).

4. Define ToolChanger2 with four slots (slots #1 and #2 will NOT be used).

5. Assign to Slot #3 the slot that Zeiss software calls Slot #3 (or C).

6. Assign to Slot #4 the slot that Zeiss software calls Slot #4 (or D).

The proper INI settings for the DSE tool changer are:

[ZEISS]

TCDepthClearance = -47.360000

TCLengthClearance = 31.800000

TCVerticalClearance = 153.750000

TCVerticalStroke = 10.000000

TCLengthInFrontOfSlot = 120.000000

TCVerticalDropToRealDropoff = 112.000000

TCLengthBackOutOfSlot = 15.000000

TCUsingCalibrationTool = TRUE

Note that these values were used with older versions of PC-DMIS (for example, version 2.X).

An example of such systems is shown below. This is the left-hand side of a GPIB based dual arm system which has a 4 slot toolchanger. The front 2 slots (here shown as C and D) must be defined within PC-DMIS as one toolchanger and the rear 2 slots (A and B) must be another.

Single Arm Ccalibration

To do a single arm calibration consider slot 3 of the right-hand arm on a UDP based dual arm system. Select the PC-DMIS tool calibration dialog as follows: -

Select the calibration tab as follows: -

Ensure the correct probe changer, slot, and tip angle is selected are displayed and hit the calibrate button. The following message is displayed: -

Hit the OK button and the following message is displayed: -

Assuming it is safe to do so hit the OK button and the following message is displayed: -

Use the jog box to disable the current tool, manually remove the tool, manually insert the calibration tool, and use the jog box to enable the calibration tool, and then use the jog box joystick controls to move the calibration tool into position at slot 3 as shown below. See later for details of jog box manual tool changing controls: -

In this case Slot 3 is clearly marked and below it slots 4 can be seen with a tool present. The side view is shown below.

On the right-hand side of the picture slot, 1 can be seen with a tool present. It is possible to manually drop tools into and lift them out of the toolchangers if necessary. Slot 2 is below slot 1 and this pair is defined in PC-DMIS as toolchanger 1 with head angles A=-90, B=-90.

When calibrating the calibration, the tool should be flush with the front of the toolchanger and the marks should line up accurately as shown below: -

Hit the OK button when in position and inspect new coordinates in the slots tab of the dialog. Note that slots 1 and 2 are redundant for probe changer 2.

If the cursor in the Edit window of PC-DMIS is positioned before any probe is defined

The coordinates in the dialog should agree with the current coordinates displayed by PC-DMIS in the Probe Readouts window. In this case, our slot 3 calibration verifies nicely.

Finally, update the dialog to define the required tool for each slot. In this case, C5A1 will be stored in slot 4 and slot 3 will remain unused.

Note that slots 3 and 4 need not be included for toolchanger 1: -

Multiple Arm Calibration

In a dual arm system (such as the one above) it is preferable to calibrate toolchangers for both arms from the Master (Arm1) PC. For this select multiple arm mode as shown below: -

Select the arm on which calibration is required using the red/green buttons: -

Switching to Master(Arm1) the probe changer calibration dialog allows calibration of the Master toolchangers: -

Switching to the Slave(Arm2) the probe changer calibration now allows calibration of the Slave toolchanger: -

Jog Box Manual Tool Changing Controls

On Zeiss GPIB systems the jog box looks as follows:

Use the TAST_AB and TAST_AUF buttons to disable and enable tool during manual changes.

For Zeiss UDP systems the jog box looks as follows: -

In this case (after hitting F1 to enable the jog box, if necessary) use the 2nd and 3rd down buttons on the right-hand side to disable and enable tool during manual changes.
